Peripherals/Energy Storage

From OLPC

In an environment where grid power may only be available for a few hours a day, or where energy generation is available but either generation or usage isn't constant an energy storage system is required.

A desirable storage technology would allow easy top-up and extraction of electricity. The input to the storage system wouldn’t necessarily need to be electrical but it would be preferable not to require a distribution system to be implemented.

For example, zinc-air fuel cells offer some interesting advantages over standard batteries, but require a zinc distribution system to be setup in conjunction with the technology.
